newjerseyrunner,
Please don't get upset with me! What I'm not understanding is, we see the angular separation with our eyes. it could be a few, to many K-ly's. (even though it appears and looks like a short distance between those two stars, to us.) But it's really ly's, (assume for this model...
Russ,
russ_watters, Please don't get upset with me! What I'm not understanding is, we see the angular separation with our eyes. it could be a few, to many K-ly's. (even though it appears and looks like a short distance between those two stars, to us.) But it's really ly's, (assume for this...
sophiecentaur, and russ_watters, Please don't get upset with me! What I'm not understanding is, we see the angular separation with our eyes. it could be a few, to many K-ly's. (even though it appears and looks like a short distance between those two stars, to us.) But it's really ly's...
Would it be correct to say, the distance we see between stars 'represents' or 'implies' ly's? And if that's true, how can we still see the light from those stars? Or is that a whole different question, (beacuse the light is constantly traveling towards us!)
My initial confusion and lack of ability to grasp how we can 'see' ly's of distance when looking at the distance we see between stars, that would take x-K ly's to travel to, if we could travel at the sol, just did not compute!
Hi Bob, Thank you for your great analogy. My model meant to suggest the 'span' - 'separation' we see between two stars ,is the distance between them, (be it 4 ly or x+K of ly's!), to state the obvious. I've since learned that this is known as 'Angular Distance', an astronomical term used to...
If I may respectfully address your commets. (Reply) 1. You can't imagine why I would think the distance between stars would matter? (Then why do astronomers tell us that certain stars and galaxies are 4, 20, 500, 1000's of lightyears away from us?) 3. Doesn't light from a star travel in all...
I think there has been some has misunderstanding of my question, or I'm not explaining it well. It appears people are responding and answering different questions I never asked on different topics I did not ask about! I'll try one more time! My apologies for my lack of understanding of light...
If I may respectfully address your comments. (Reply) 1. You can't imagine why I would think the distance between stars would matter? Then why did they call it Leavitt's Law? Isn't that why do astronomers tell us that certain stars and galaxies are 4, 20, 500, 1000's of lightyears away from...
Yes, it is difficult to state simply. But once you see what I mean you'll get that (Ah, that's what he means, moment!) Like I'm trying for with this question! LOL! Try this senario, please. You're standing outside on a clear night. You look up and see a sky full of stars. You pick one...
Drakkith, Thank you. Well said! OK, I get that. But what I'm not getting is the 'distance' between the stars (thousands of light years) from one star to another that we see when we look at one point of light, (a star) in the sky, and then scan our eyes to the opposite point in the night sky...
Thank you for your response. Yes, I understand we are seeing 'old' light from stars. Some of which may have in fact died long ago, so were actually seeing the light traveling from them, after they burned out, not the actual star. But aren't we 'seeing' light from stars only when it comes...
Leavitt's Law allows us to determine how far stars are from us by calculating their variable magnitude of brightness. Please explain how it's possible then for us to see, with the 'natural eye', the distances from one star to another, from one point in the night sky to the opposite, that would...
